    I tied re-bar with a construction in Boston about 20 years ago and I recommended adding an electrical current to the re-bar that prevented the concrete from falling below the freezing point. We tried this at a large project on the Boston waterfront that supported container ship cranes. I want to find out how much value this innovation is. I have a Mass. construction license that this is mentioned and I am not allowed to see this. Can someone verify what I am looking for. The company is not is business. I was a member of  ironworkers local#7 Boston. The amount of snow that has to be moved in the winter is expensive. I want to know if this method is cost effective. I am 58 now. Does anyone know Modern Continental Construction? I know they knew. My signature was with them on a project that has some industrial design. Thank You Donald K Roche.    donroche@....

    ​Morning Donald,

    There has been quite a bit of work done on heated pavements over the years in many countries.  The Netherlands has constructed "ModiSlab" https://trid.trb.org/view.aspx?id=778796.  Professor Halil Ceylan from Iowa State University has done a lot of work on this as well.  He has published quite a few papers on the subject.  One presentation below.

    We developed a graphite asphalt that has been successful in a number of placements in Finland and had been installed at Chicago O'Hare on a taxiway (now removed).  We had 250,000 aircraft movements without any issues and zero maintenance.
